Description

[Technical field]

[0001] The present invention relates to a pipe support fitting. [Background technology]

[0002] Pipe support fittings are used to suspend and support pipes connected to water supply equipment, air conditioning equipment, etc., in structures such as slabs that constitute the ceiling of a building.

[0004] [Patent Document 1] Patent Publication No. 2022-75177 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in this configuration, when supporting a pipe using the pipe support fitting, it is necessary to remove the fastening members, open the pair of divided supports, close the pair of divided supports while supporting the pipe, and then attach the fastening members again to fasten them, which leaves room for improvement in terms of workability. Also, in general, it is required to firmly fix a pipe when supporting it.

[0006] Therefore, it is desirable to develop a pipe support fitting that is easy to install and can firmly fix pipes. [Means for solving the problem]

[0007] The pipe support fitting according to the present invention comprises: A pipe support fitting for suspending and supporting a pipe on a structure, A mounting portion is attached to a hanging rod-like body suspended from the structure, and a support portion is connected to the mounting portion to support the piping, the support portion includes a first divided body which is an integral whole, and a second divided body having an upper portion and a lower portion which are pivotally connected to each other, an upper end side of the first division and the upper portion of the second division are connected to the mounting portion by a fastening member, and a lower end side of the first division and a swing end of the lower portion of the second division are freely engaged and disengaged, and in this engaged state, the first division and the second division surround the entire circumference of the piping, The first division is provided with a movement restricting portion that restricts relative upward movement of the piping inside the support portion when the fastening member is fastened.

[0008] According to this configuration, the support portion is composed of a first divisional body and a second divisional body, of which the second divisional body is configured to be freely swingable, so that the piping can be attached while maintaining the first divisional body and the second divisional body that constitute the mounting portion and the support portion connected to each other. After the piping is attached, the lower end side of the first divisional body and the swing end of the lower portion of the second divisional body are engaged to appropriately support the piping. This improves the ease of installation when suspending and supporting the piping on a structure.

[0009] In order to initially engage the lower end of the first division with the swing end of the lower portion of the second division, an upper space is required inside the support section to allow the pipe to be raised slightly. When the fastening member is fastened after the pipe is supported, the support section shrinks in diameter, and the reduced diameter support section clamps and fixes the pipe inside, but the presence of the upper space may reduce the fixing force of the pipe. In this regard, in the present configuration, the movement restriction section provided on the first division restricts the relative upward movement of the pipe inside the support section when the fastening member is fastened, so the fastening force of the fastening member is hardly offset to eliminate the upper space. Therefore, the pipe can be firmly fixed.

[0010] Preferred embodiments of the present invention will be described below. However, the scope of the present invention is not limited to the preferred embodiments described below.

[0011] In one embodiment, It is preferable that the movement restricting portion is configured by a portion of the first split body that protrudes radially inward.

[0012] With this configuration, with a simple configuration of merely protruding a portion of the first partition radially inward, the relative upward movement of the piping inside the support portion when the fastening member is fastened can be restricted.

[0013] In one embodiment, The first division body has a crank-shaped arc portion that is formed in an arc shape along an outer shape of the pipe and is bent into a crank shape, It is preferable that the movement restricting portion is formed by a small diameter portion of the crank-shaped arc portion.

[0014] With this configuration, with a simple configuration of simply forming the first partition into an arc shape that follows the outer shape of the piping and then bending it into a crank shape, it is possible to restrict the relative upward movement of the piping inside the support part when the fastening member is fastened and to stably support the piping.

[0015] In one embodiment, It is preferable that the first divided body has a gently curved portion, the gently curved portion having a radius of curvature larger than the radius of the pipe, located lower than the movement restricting portion.

[0016] According to this configuration, when the support portion, which is reduced in diameter by fastening the fastening member, clamps the pipe inside, the pipe is allowed to move downward relative to the support portion. This makes it difficult for the lower end of the first division and the swing end of the lower portion of the second division to come out of engagement. Therefore, the pipe can be supported appropriately.

[0017] Further features and advantages of the present invention will become more apparent from the following description of exemplary and non-limiting embodiments, which are given with reference to the drawings. [Brief description of the drawings]

[0019] An embodiment of a pipe support fitting will be described with reference to the drawings. As shown in Fig. 1, a pipe support fitting 1 of this embodiment is used to suspend and support a pipe P from a structure S. The pipe support fitting 1 is attached to a suspension bolt B suspended from a structure S such as a slab constituting a ceiling, and suspends and supports the pipe P in a horizontal position.

[0020] The hanging bolts B are arranged along the installation direction of the pipe P. A plurality of hanging bolts B are installed at a predetermined interval at a plurality of locations along the installation direction of the pipe P, and the pipe P is suspended and supported over the entire installation direction by the pipe support fittings 1 attached to each hanging bolt B. As the hanging bolts B, a fully threaded bolt that is threaded over the entire length may be used, or a double-threaded bolt that is threaded only at both ends may be used. In this embodiment, the hanging bolts B correspond to a "hanging rod-shaped body."

[0021] 1 and 2, the pipe support fitting 1 includes an attachment part 2 that is attached to a hanging bolt B, and a support part 3 that supports a pipe P. The attachment part 2 and the support part 3 are connected by a fastening member 6. The fastening member 6 includes a fastening bolt 61 and a fastening nut 62 that is screwed into the fastening bolt 61.

[0022] The mounting portion 2 is a portion for attaching the support portion 3 to a suspension bolt B suspended from the structure S. As shown in Fig. 2, the mounting portion 2 in this embodiment is configured by a turn buckle 20. The turn buckle 20 has a mounting plate 21 and a pair of connecting plates 22 extending downward from the mounting plate 21.

[0023] The mounting plate 21 is a portion that is attached to the hanging bolt B. The mounting plate 21 is formed in a rectangular shape. An insertion hole 21a is formed through the center of the mounting plate 21. A flanged nut N is inserted into this insertion hole 21a from the inside. The inner diameter of the insertion hole 21a is smaller than the flange of the flanged nut N, and the mounting part 2 is attached to the hanging bolt B in a form supported by the flange of the flanged nut N that screws onto the hanging bolt B. Note that instead of the flanged nut N, the mounting part 2 may be attached to the hanging bolt B by, for example, an upper and lower double nut.

[0024] The connecting plate 22 is a portion that is connected to the support part 3. In this embodiment, a pair of connecting plates 22 are provided so as to extend downward from a pair of opposite sides of the rectangular mounting plate 21. Each of the pair of connecting plates 22 is bent at two points to form a gentle crank shape so that the distance between the lower end side (opposite the mounting plate 21) is narrower than the upper end side (the mounting plate 21 side). An insertion hole 22a is formed through the connecting plate 22 near the lower end. A shaft portion 61B of a fastening bolt 61 that constitutes the fastening member 6 is inserted into the insertion hole 22a.

[0025] The support part 3 is a part connected to the mounting part 2 to support the pipe P. As shown in FIG. 2, the support part 3 in this embodiment is divided into left and right parts, and has a first division body 30 and a second division body 40. In this embodiment, the pair of division bodies, the first division body 30 and the second division body 40, have an asymmetric structure. The first division body 30 is constructed as a whole. The second division body 40 has an upper part 41 and a lower part 51 connected to be able to swing freely.

[0026] The first divided body 30, which is an integral whole, has, in order from the top, a flat plate connecting portion 31, a crank-shaped arc portion 32, a gently curved portion 33, and a fixed engagement portion 34. These are integrally formed by, for example, pressing using a strip-shaped steel plate.

[0027] The flat plate connecting portion 31 is a flat plate-like portion located at the upper end side of the first divided body 30, and is the portion that is connected to the mounting portion 2. The flat plate connecting portion 31 is formed in a rectangular shape (specifically, a rectangular shape). The flat plate connecting portion 31 is arranged along the up-down direction. An insertion hole 31a is formed through the flat plate connecting portion 31 slightly above the center. A shaft portion 61B of a fastening bolt 61 that constitutes the fastening member 6 is inserted into this insertion hole 31a.

[0028] The crank-shaped arc portion 32 is formed in an arc shape as a whole so as to extend from the lower end of the flat plate connecting portion 31 along the outer surface of the pipe P. The crank-shaped arc portion 32 is formed in an arc shape as a whole, but is bent at two points to form a gentle crank shape. The crank-shaped arc portion 32 has an arc-shaped large diameter portion 32A, an arc-shaped small diameter portion 32B that is located below the large diameter portion 32A and has a smaller diameter than the large diameter portion 32A, and an oblique portion 32C that connects them. In this embodiment, by having such a crank-shaped arc portion 32, an upper space U is generated inside the large diameter portion 32A due to the difference in inner diameter between the large diameter portion 32A and the small diameter portion 32B (see FIG. 4).

[0029] The gently curved portion 33 extends downward from the lower end of the small diameter portion 32B of the crank-shaped arc portion 32. The gently curved portion 33 is formed so that the radius of curvature is larger than the radius of the pipe P. In this embodiment, the gently curved portion 33 is formed in a flat plate shape with an infinite radius of curvature. Thus, in this embodiment, the gently curved portion 33 does not necessarily have to be curved, and may be flat. In this embodiment, by having such a gently curved portion 33, a lower space L is generated inside the gently curved portion 33, in which the gap with the pipe P gradually increases toward the bottom (see FIG. 4).

[0030] The fixed engagement portion 34 extends obliquely downward from the lower end of the gently curved portion 33. The fixed engagement portion 34 is a portion for engaging with the lower portion 51, which is the portion of the swingable second division 40 on the swingable side. The fixed engagement portion 34 is generally formed in a flat plate shape, and a locking piece 34A is cut and raised toward the inside near the lower end. This locking piece 34A locks into a through hole 54a formed in the movable engagement portion 54 of the lower portion 51 of the second division 40. In addition, an engagement guide portion 34B is provided on the tip side of the locking piece 34A in the fixed engagement portion 34. The engagement guide portion 34B is gradually inclined outward toward the tip. The engagement guide portion 34B guides the engagement between the locking piece 34A and the through hole 54a.

[0031] The second divided body 40 has an upper part 41 and a lower part 51 which are connected so as to be able to swing freely. The upper part 41 and the lower part 51 are connected so as to be able to swing freely around a pivot member 46. Examples of the pivot member 46 include a rivet, a pin with a retaining structure, and a loosely fastened bolt and nut, and in this embodiment, a rivet is used.

[0032] The upper portion 41 has a flat plate connecting portion 42, a curved portion 43, and a loop portion 44. These are integrally formed by, for example, pressing using a strip-shaped steel plate.

[0033] The flat plate connecting portion 42 is a flat plate-shaped portion located at the uppermost position of the upper portion 41 of the second division body 40, and is a portion that is connected to the mounting portion 2 together with the flat plate connecting portion 31 of the first division body 30. The flat plate connecting portion 42 is formed in a rectangular shape (specifically, a rectangular shape). The flat plate connecting portion 42 is arranged along the up-down direction. An insertion hole 42a is formed through the flat plate connecting portion 42 slightly above the center. The shaft portion 61B of the fastening bolt 61 that constitutes the fastening member 6 is inserted into this insertion hole 42a.

[0034] The curved portion 43 extends in an arc shape from the lower end of the flat plate connecting portion 42. In this embodiment, the curved portion 43 is formed in an arc shape having a central angle of approximately 60° when viewed from the front.

[0035] The loop portion 44 is provided at the lower end of the curved portion 43, continuing from the curved portion 43. The loop portion 44 is looped on the outer surface side of the curved portion 43. One loop portion 44 is provided at the center portion of the lower end of the curved portion 43, excluding both side portions in the width direction. Two loop portions 53 are arranged in the lower side portion 51 on both sides of the loop portion 44.

[0036] The lower portion 51 has a curved portion 52, a loop portion 53, a movable engagement portion 54, and an extension portion 56. These are integrally formed by using a strip-shaped steel plate, for example, by pressing.

[0037] The curved portion 52 is a main portion of the second division body 40 that supports the pipe P. The curved portion 52 is curved in an arc shape. The curved portion 52 supports the pipe P in a state of contacting the pipe P from below.

[0038] The loop portion 53 is provided on the upper end of the curved portion 52, continuing from the curved portion 52. The loop portion 53 is looped on the outer surface side of the curved portion 52. Two loop portions 53 are provided, separated into two portions on both sides in the width direction of the upper end of the curved portion 52. The loop portion 44 of the upper portion 41 is disposed between the pair of loop portions 53. A pivot member 46 is inserted between the two loop portions 53 of the lower portion 51 and the loop portion 44 of the upper portion 41, so that the upper portion 41 and the lower portion 51 can freely swing around the pivot member 46 as an axis.

[0039] The movable engagement portion 54 is provided on the lower end side of the curved portion 52. The movable engagement portion 54 is formed with a larger diameter than the curved portion 52. The movable engagement portion 54 is formed with a larger diameter by being offset outward from the curved portion 52 by approximately several plate thicknesses. A through hole 54a is formed in the movable engagement portion 54. A locking piece 34A provided on the fixed engagement portion 34 of the first division 30 engages with this through hole 54a.

[0040] The extension portion 56 extends upward from the curved portion 52. The extension portion 56 extends from the curved portion 52, past the loop portion 53, to a position where it overlaps with the upper portion 41. The extension portion 56 is provided in the center in the width direction, between the two loop portions 53. The extension portion 56 is curved in an arc shape, and is disposed along the inner surface of the curved portion 43 of the upper portion 41 when the first division 30 and the second division 40 are closed.

[0041] In this embodiment, the upper end side of the first division 30 and the upper portion 41 of the second division 40 are connected to the mounting portion 2 by the fastening member 6, and the upper portion 41 and the lower portion 51 of the second division 40 are connected so as to be able to swing freely. Therefore, while the first division 30 and the upper portion 41 of the second division 40 are fixed, the lower portion 51 of the second division 40 swings. With this swing, the support portion 3 can change its position between an open position in which the first division 30 and the second division 40 are open downward, and a closed position in which the first division 30 and the second division 40 are closed.

[0042] In this embodiment, the lower portion 51, which is connected to the upper portion 41 so as to be freely swingable, has an extension portion 56. Therefore, as can be seen from Figure 3, by simply inserting the piping P from below into the inside of the support portion 3 in the open-ring position, the support portion 3 changes from the open-ring position to the closed-ring position in conjunction with the installation of the piping P.

[0043] Furthermore, the lower end side of the first division 30 and the swing end of the lower portion 51 of the second division 40 can be freely engaged and disengaged by the locking piece 34A of the fixed engagement portion 34 and the through hole 54a of the movable engagement portion 54. When these are engaged (hereinafter referred to as the "engaged state"), the support portion 3 is in a closed position, and the first division 30 and the second division 40 surround the pipe P all around to support the pipe P. These factors combine to greatly improve the ease of construction when supporting the pipe P by suspending it on the structure S.

[0044] Incidentally, when attaching the pipe P to the support part 3, the movable engagement part 54 needs to climb over the locking piece 34A before the locking piece 34A of the fixed engagement part 34 and the through hole 54a of the movable engagement part 54 finally come into engagement with each other. To achieve this, it is necessary to have a marginal space inside the support part 3 that allows the pipe P to rise somewhat. In this regard, in the present embodiment, the first divided body 30 has the crank-shaped arc part 32, and thus an upper space U into which the pipe P can enter is generated inside the support part 3 as shown in FIG. 4, so that the locking piece 34A and the through hole 54a can be appropriately engaged to take the closed position.

[0045] After the pipe P is supported by the support part 3 in the closed position, the fastening member 6 is fastened to firmly fix the pipe P, as shown in Fig. 5. In this embodiment, a fastening bolt 61 and a fastening nut 62 screwed thereto are used as the fastening member 6. The fastening nut 62 is screwed onto the shaft part 61B of the fastening bolt 61 and tightened, and the two connecting plates 22, 22 and the two flat plate connecting parts 31, 42 are sandwiched and fixed between the head part 61A of the fastening bolt 61 and the fastening nut 62.

[0046] To facilitate such a fastening operation, the pipe support fitting 1 of this embodiment is provided with an auxiliary tool 7 that is attached to the connection point between the attachment part 2 and the support part 3. As shown in Figures 2 and 3, the auxiliary tool 7 has a base plate 71, an arm part 72, a locking claw 73, a shielding wall 74, and a cover part 75. The auxiliary tool 7 can be integrally formed by injection molding using, for example, a resin material.

[0047] The base plate 71 is formed in a flat plate shape that fits along the outer surface of the flat plate connecting portion 31 of the first section 30. An insertion hole 71a is formed penetrating the base plate 71. The insertion hole 71a is formed in a regular hexagon shape that corresponds to the outer shape of the fastening nut 62 that constitutes the fastening member 6. The shaft portion 61B of the fastening bolt 61 that constitutes the fastening member 6 is also inserted into this insertion hole 71a.

[0048] A pair of arm portions 72 are provided so as to extend from both ends of the base plate 71 in the width direction. The pair of arm portions 72 each extend at a substantially right angle from the base plate 71 and are arranged parallel to each other. Hook-shaped locking claws 73 are formed on the tips of the pair of arm portions 72 (the ends opposite the base plate 71). These locking claws 73 lock onto the outer surface of the flat plate connecting portion 42 of the second divided body 40 when the auxiliary device 7 is attached to the fixing portion 5. This makes it possible to prevent twisting of the first divided body 30 and the second divided body 40.

[0049] The shielding wall 74 is provided on the surface of the base plate 71 opposite to the arm portion 72. The shielding wall 74 in this embodiment is formed in a generally regular hexagonal cylindrical shape corresponding to the shape of the insertion hole 71a, and the fastening nut 62 constituting the fastening member 6 is fitted into this shielding wall 74. This makes it possible to prevent the fastening nut 62 from rotating together with the fastening bolt 61, and the fastening operation can be easily performed.

[0050] The lid portion 75 is provided so as to be able to cover the upper opening of the shielding wall 74. The lid portion 75 is formed in a regular hexagonal shape corresponding to the shape of the shielding wall 74. The lid portion 75 can be opened and closed by swinging about the upper side as a fulcrum. When the fastening operation of the fastening member 6 is completed, the tip of the fastening bolt 61 protrudes from the shielding wall 74 and the lid portion 75 opens and is disposed at an angle as shown in Fig. 5, so that the completion of the fastening operation can be visualized and easily confirmed.

[0051] Further, in this embodiment, as shown in FIG. 5, when the fastening member 6 is fastened, the small diameter portion 32B of the crank-shaped arc portion 32 of the first divided body 30 abuts against the pipe P from above at an angle, restricting the upward relative movement of the pipe P inside the support portion 3. Therefore, the fastening force of the fastening member 6 is hardly offset to eliminate the upper space U, and the pipe P can be firmly fixed. In addition, a lower space L is formed inside the gently curved portion 33, in which the gap with the pipe P gradually increases as it goes downward, so that the pipe P pressed by the small diameter portion 32B is allowed to move downward relative to the pipe P, and further presses the lower portion 51 of the second divided body 40. As a result, the engagement between the locking piece 34A of the fixed engagement portion 34 and the through hole 54a of the movable engagement portion 54 becomes stronger, and the pipe P can be properly supported.

[0052] In this embodiment, the movement restricting portion R is configured by a small diameter portion 32B of the crank-shaped arc portion 32, which is a part of the first segment 30 and also a portion that protrudes radially inward.

[0053] 6 shows a pipe support fitting 100 of a comparative example. This pipe support fitting 100 includes an attachment portion 102 and a support portion 103 that are connected to each other, and the support portion 103 includes a first division body 130 and a second division body 140. The second division body 140 includes an upper portion 141 and a lower portion 151 that are connected to be able to swing freely, and the first division body 130 and the second division body 140 surround the entire circumference of the pipe P with the lower end side of the first division body 130 and the swing end of the lower portion 151 of the second division body 140 engaged. These basic configurations are the same as those of the pipe support fitting 1 of the above-mentioned embodiment.

[0054] However, the pipe support fitting 100 of the comparative example does not have the movement restricting portion R that the pipe support fitting 1 of the embodiment has. Therefore, even if the fastening member 6 is fastened, the fastening force is first used to reduce the upper space U, and the fixing force of the pipe P is reduced accordingly. In addition, the first division body 130 of the pipe support fitting 100 of the comparative example has a movement restricting portion Q (specifically, a step portion) at a position close to the engagement portion with the lower portion 151 of the second division body 140, which restricts the relative downward movement of the pipe P inside the support part 3. Therefore, when the fastening operation of the fastening member 6 is further advanced, the lower portion 151 of the second division body 140 is pushed by the pipe P that moves relatively upward and rotates further in the closing direction. As a result, the engagement between the lower end side of the first division body 130 and the swing end of the lower portion 151 of the second division body 140 is easily released.

[0055] From these comparisons, it can be seen that the pipe support fitting 1 of this embodiment is equipped with a movement restricting portion R that restricts the relative upward movement of the pipe P inside the support portion 3, and also has a gently curved portion 33 that forms the lower space L, thereby enabling the pipe P to be securely and firmly fixed.

[0056] Other embodiments (1) In the above embodiment, an example has been described in which the movement restricting portion R is formed by the small diameter portion 32B of the crank-shaped arc portion 32. However, the present invention is not limited to such a configuration, and for example, a rib-like protrusion that protrudes inward may be provided on the first divided body 30, and the movement restricting portion R may be formed by the rib-like protrusion. Alternatively, a part of the first divided body 30 may be cut and raised inward, and the movement restricting portion R may be formed by the cut and raised portion.

[0057] (2) In the above embodiment, an example has been described in which the movement restricting portion R is configured by utilizing the shape of a portion of the first divided body 30. However, the present invention is not limited to such a configuration, and the movement restricting portion R that is separate from the first divided body 30 may be fixed to the inside of the first divided body 30.

[0058] (3) In the above embodiment, an example has been described in which the pipe support fitting 1 has the gently curved portion 33. However, the present invention is not limited to such a configuration, and the pipe support fitting 1 may not have the gently curved portion 33, and the portion may be a curved portion that curves with the same radius of curvature as the radius of the pipe P.

[0059] (4) The specific configuration of the mounting portion 2 described in the above embodiment is merely an example and is not limited to such a configuration. For example, the mounting portion 2 may be configured as an L-shaped bent plate or the like.

[0060] (5) In the above embodiment, the mounting portion 2 and the support portion 3 are separate bodies. However, the present invention is not limited to such a configuration, and the mounting portion 2 and the support portion 3 may be integrally connected.

[0061] (6) The configurations disclosed in the above-mentioned embodiments (including the above-mentioned embodiments and other embodiments; the same applies below) can be applied in combination with configurations disclosed in other embodiments, as long as no contradiction occurs. As for other configurations, the embodiments disclosed in this specification are illustrative in all respects and can be appropriately modified within the scope of the present disclosure.
